Top pair with a weak kicker on Jd5dKc should mostly check, and once we bet small twice, the river Qs is a card where we should check and let villain bluff.
Flop Jd5dKc gives us top pair with a weak kicker on a semi-wet, two-tone board. Solver leans heavily toward checking this combo, with some medium bets and very few small bets; the small c-bet works in practice but is slightly off the theoretical plan.
Note: Small c-bet with top pair weak kicker on Jd5dKc is slightly off the preferred strategy; checking this combo more often is higher EV.
Turn 3c adds a second club and improves villain’s range; with SPR ~3, checking top pair more often is preferred, but a small bet is still reasonable. We’re targeting folds from weaker pairs and random overcards while not overcommitting versus flushes and strong made hands.
River Qs is a very connected card that improves villain’s range; solver wants this exact combo to check almost always. The small bet is a small mistake—checking lets villain bluff their missed draws and random overcards, and we still get paid by worse Kx and some Jx/5x that don’t fold.
Note: River Qs is a card where top pair with a weak kicker should mostly check; the small bet is a small EV loss versus a range that now contains more strong made hands.
